摘要
目的:通过对天花粉蛋白基因工程菌T239发酵条件研究,优化培养及表达条件。方法:研究温度、PH值、培养时间、培养基成分、接种量、诱导剂浓度等6种因素对于表达量的影响。结果:天花粉蛋白基因工程菌T239发酵条件在温度30℃、pH值7.3、摇床转速200r/min、50ml/500ml培养瓶、接种量3%、培养时间30h、添加葡萄糖浓度为2.0g/L时,表达量最高。
Objective: Engineering Strain(T239) was cultivated under different conditions in order to find the optimal Fermentations that would lead to maximal fusion protein yield. Methods: The strain was cultured under different temperature, pH, rotating rate, time, and capability of bottle. Results and conclusions: The proper Fermentation Conditions consist of: 30℃, pH7.3,200r/min, 50ml/500mlculture bottle, 30h, rotating cultivation bed, with 2.0g/L glucoseon added.
